The reason why the natal magic weapon is called the natal magic weapon is that it has growth, and all the natal magic weapons will grow with the growth of the master, to put it bluntly, it is advanced.

A magic weapon and the essence and blood in the master's body are fused into one and become a part of the master's body, which is called the natal magic weapon, and the most important step is the fusion of essence and blood.

The magic weapon has a drop of blood to recognize the master, but I don't know that this is just a relative to the general magic weapon, like the extreme fire sword refined by Li Chong at the moment, the average Jindan monk can use it as long as he drops in the essence blood to refine and fuse it at will, and it is much more troublesome to become a natal magic weapon, to completely integrate the magic weapon with his own body, and the so-called fusion must not only be fused with the essence and blood of the body, but also match the ** cultivated.

There is a magic weapon to recognize the law of the Lord Li Chong did not deliberately look for it, the Burning Heaven Decision recorded a kind of mysterious law decision, called 'Tong Ling Technique' is a kind of magic weapon specially used to control zhì magic weapon, Li Chong is not saying that he does not want to find other law decisions, but because of how can the ordinary law decisions be comparable to the law decisions in the Supreme Treasure Book.

Li Chong's hands formed three mystical magic seals in the Linglon Technique, and three huge light runes condensed out from in front of him, and then all of them were smashed into the Extreme Fire Sword one by one, and the moment the Extreme Fire Sword was smashed into the runes, the whole body was involuntarily trembling.

Seeing this, Li Chong's mind was full of thoughts, and a swarm of bees poured into the sword body, according to the method recorded in the Tongtong Technique, Li Chong planted his own divine consciousness imprint in it, and the moment the imprint was formed, Li Chong in the Extreme Fire Sword clearly sensed all of his brain, as if this sword was a part of his body, and he was just looking at his own body.

After doing this, Li Chong immediately opened his mouth and spit out his three-color golden pill, and under Li Chong's deliberate control, all the three-color golden pills turned into fiery red, and the burning innocent fire came out, suspended in the sky above the Extreme Fire Sword, and the Extreme Fire Sword seemed to be able to sense the storage of the golden pill, and the whole body turned into a dark red flame and fused with the golden pill.

The moment Jin Dan and the Extreme Fire Sword fused, Li Chong's eyes burned with innocent fire, and nine runes symbolizing the nine great fire spirits of the Brahma Fire Spirit Technique were condensed one by one, all of which were integrated into the Extreme Fire Sword.

"Natal essence blood, fusion!" After doing this, Li Chong took the Extreme Fire Sword and re-inhaled Jin Dan into his body, the first time Jin Dan returned to the dantian, Li Chong sealed his hands and shouted at the same time.

The Extreme Fire Sword in Li Chong's dantian re-transformed from a flame state to a substance, the difference was that the appearance had shrunk many times, but it was the size of a small thumb, and it was circling around Li Chong's golden pill.

At this time, there were nine more mystical runes on the Extreme Fire Sword, and the dragon, the phoenix, the lion, the tiger, the ape, and the nine great fire spirits of the Golden Crow were flying, exuding the aura of the arcane extreme fire, and at the same time, a rich Burning Heaven True Fire clearly diffused out on it, which was much stronger than when it was first refined before.

Suddenly, a terrifying attraction on the Extreme Fire Sword burst out, Li Chong was shocked, and he clearly sensed that the essence blood in his body was surging rapidly, and after a while, a large amount of essence blood in his body was pulled out, all of which surged towards the Extreme Fire Sword.

The attraction of the Extreme Fire Sword became bigger and bigger, but it swallowed up a large amount of Li Chong's essence blood in an instant, and the Extreme Fire Sword, which devoured a large amount of essence blood, condensed a quaint blood-colored rune on it, and with the condensation of this rune, Li Chong immediately felt the feeling of being connected with the Extreme Fire Sword and his own flesh and blood, which was the true reaction of the natal magic weapon and the master, that is to say, the Extreme Fire Sword had successfully fused with Li Chong.

"Three points in one! Yuan Shen brand, Cheng!" Li Chong formed a magic seal again, and directly submerged into the Burning Sky Extreme Fire Sword, the blood-colored runes on the Burning Sky Extreme Fire Sword rose with blood, and once again devoured Li Chong's essence blood, after half a cup of tea, the Burning Sky Extreme Fire Sword did not eat more or less exactly swallowed one-third of Li Chong's essence blood, and at the same time, the feeling that Li Chong and the Extreme Fire Sword were connected with flesh and blood became clearer and clearer.

After devouring one-third of the essence blood, the blood-colored rune on the Extreme Fire Sword was completely condensed, and at the same time, a rune in Li Chong's Divine Consciousness Sea that was exactly the same as the blood-colored rune on the Extreme Fire Sword was manifested, which was the divine second manifestation of the Tongtong Technique.

After doing this, Li Chongchang breathed a sigh of relief, at this time, because he lost one-third of his essence blood, his breath was chaotic, and his face was even paler, but he did not have a trace of haze, but was excited.

"Come out!" Li Chong grinned, the flames in his hand rose, and the Burning Sky Extreme Fire Sword instantly turned out, and the moment the sword came out, a blazing high temperature suddenly filled the entire secret room.

"Go!" Li Chong's mind moved, and the wind array on the Extreme Fire Sword immediately opened, and at the same time, the sword in his hand disappeared instantly, and the next moment, a wall of the secret room flashed, and a light array was triggered out of thin air, and in front of the light array, the tip of the Extreme Fire Sword was dead against the light array, and the speed of the sword attack was almost equivalent to teleportation, and the effect of the Wind Array after the transformation of the Burning Sky Supreme could be seen.

"Ten times increase!" Li Chong's divine thought moved again, and the sword Heavenly Weeping Formation opened, and at the same time, the spiritual power in his body was rapidly consumed, and all the true yuan in his dantian was drained almost instantly.

"Boom!" A roar erupted in the secret room, and the Extreme Fire Sword that was originally resisting the light array suddenly burst into flames, and a force ten times more terrifying than before exploded instantly, directly shattering the light array, and the light array was broken, and the stone wall lost its protection, and was directly pierced by the Burning Sky Extreme Fire Sword, and the sword body was inserted into the stone wall.

"Poof!" Li Chong opened his mouth and spat out a mouthful of blood, while the boss with his eyes wide open, staring at the Extreme Fire Sword inserted in the stone wall, swallowed his saliva.

"Actually broke the protective array that only needed true god-level strength to break, wouldn't it be that the power that exploded in an instant was equivalent to the power of the true god realm, Li Chong was shocked in his heart, and the power of the extreme fire sword he refined was completely beyond his estimate.

At the same time, he smiled bitterly, because the blow just now consumed fifty percent of his spiritual power, and fifty percent of his spiritual power consumption was simply an extraordinary load.

"Brother Li! Li Chong!" A shadow quickly rushed in from outside the secret room, Chen Lingling looked anxious on her face, and looked around as soon as she came in.

"Here!" Li Chong gasped, looking at Chen Lingling with an anxious face, and a warm current flowed through Li Chong's heart.

"How did you do it, how did it become like this!" Chen Lingling quickly rushed to Li Chong's side, helped him up, and asked worriedly.

"Hahahaha, it's okay, it's just that the fusion of the natal magic weapon has lost more essence and blood, no, the true yuan has also been consumed!" Li Chong said with a smile.

"It's understandable to lose your essence and blood, but why did your true yuan be consumed!" Chen Lingling looked at Li Chong and asked as if she was curious.

"It's all that guy!" Li Chong said with a bitter expression as he pointed to the Burning Sky Extreme Fire Sword inserted in the stone wall.

"This is your natal magic weapon?" Chen Lingling looked in the direction that Li Chong was pointing, looking at the Extreme Fire Sword inserted in the wall, her face was full of shock, you must know that the protection in this secret room does not have the strength of the true god level, it cannot be broken at all, and Li Chong's sword is inserted into the wall at this moment.

"How did you do that?" asked Chen Lingling curiously.

Li Chong smiled slightly, then took out a jade slip, and Shen Nian burned something on it and handed it to Chen Lingling.

Chen Lingling's little head shook in confusion, she didn't know what medicine was sold in Li Chong's gourd, she took the jade slip and began to look at it, it doesn't matter if she doesn't look at it, her face suddenly changed when she saw it...
